The Krefeld study has shown: The extinction of species has also reached us. While one could shrug off the disappearance of an unknown species somewhere in Africa, bees, bumblebees, and beetles are now dying right at our doorstep – and with them, birds, frogs, and much more are vanishing. What we lose with the insects is not just the foundation of a healthy ecosystem; with the extinction of pollinators, the food supply for countless people is at stake. Why do we need insects? Is their disappearance just a temporary whim of nature? Who or what is responsible for this? Insect researcher Andreas Segerer explains the connections and outlines what needs to happen now. Additionally, Eva Rosenkranz provides many practical tips, as everyone can contribute to ensure that the world does not fall silent.
